UNITED STATES PATENT OFFICE.

FRANK KELLER, OF GULBERTSON, NEBRASKA.

AUTOMATIC LUBRICATOR.

SPECIFIGATION forming part of Letters Patent No. 416,062, dated November 26, 1889.

Application filed May 24, 1889. Serial No. 311,987. (No model.)

To to whom it may concern- Be it known that I, FRANK KELLER, a citizen of the United States, residing at Culbertson, in the county of Hitchcock and State of. Nebraska,have invented certain new and useful Improvements in Automatic Lubricators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in lubricators; and it has for its object to provide an automatic lubricator which shall be simple in its construction and very efiicient in operation.

The novelty resides in'the peculiar combinations and the construction, arrangement, and adaptation of parts, all as more fully hereinafter described, shown in the drawings, and then particularly pointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which- Figure 1 is a perspective view of my improvement with parts broken away. Fig. 2 is a vertical transverse section of Fig. 1.

Referring now to the details of the drawings by letter, A designates a suitable casing, within which the operating parts are arranged.

B is the oil-cup, the opening in which at the top is preferablyflush with the upper face of the bottom of the casing, as shown, while its discharge end may be arranged to extend below the bottom to any desired distance, according to the purpose to which the device is to be put. The upper end of this cup is closed by means of the valve 0, which is carried by the free end of the substantially horizontal springarm D, the other end of which is suitably secured within the casing, as shown. This valve may be of any appropriate shape and material, and may be provided with a suitable packing-disk, if desired.

valve is down, so as to completely close the opening in the cup.

Normally this E is a cross-bar orsupport within the casing, near the upper end thereof, and suitably pivoted on this support is the bell-crank lever F, the free end of the horizontal arm of which is connected with the valve 0, by means of the vertical arm G, in any suitable manner.

J ournaled in the top of the casing and the cross-bar E is the vertical spindle H, to which is secured the toothed wheel I, provided with the radial arms J, depending from the under side of one of which is a finger or lug a, arranged to contact with the free end of the vertical arm of the bell-crank lever F at predetermined intervals.

K is a spring-metal arm fixed at its lower end in suitable fixtures, as shown, and its upper end, after passing through the cross-bar E, is left free and has attached thereto the horizontal arm or lever L, the inner end of which is sharpened or beveled, as shown,and adapted to engage the teeth of the wheel I. This connection maybe made in any suitable manner. In the drawings I have shown the lever L as provided with a transverse groove K,-i.nto which the upper end of the arm K fits, and is secured by soldering or otherwise.

M is a flat spring attached at one end to the casing, and its other end adapted to bear on the toothed wheel, as shown, to prevent retrograde movement thereof.

N is the inlet-opening into the casing.

In practice the arm or lever L is designed to be connected with some moving part of the machinery which it is designed to lubricate-- as, for instance, the pump-rod ot' a windwheel-in such a'manner that as the rod or other part reciprocates or revolves the arm L will be given a movement in the direction of the arrow in the drawings, and as the said arm returns to its normal position it will engage the teeth of the wheel and move it one notch. The torsion of the spring-arm K will serve to return the arm L to its normal position. \Vhen the wheel has moved notches enough to bring the lug a in contact with the vertical arm of the bell-crank lever, it will move the same in the direction of the arrow, and thus lift the valve and allow the flow of a given amount of oil to the parts to be lubricated through the discharge-opening of the oil-cup. As soon as the lug has passed the end of the bell-crank lever the arm assumes its normal position until again actuated by the said lug. If it be desired to have a flow of oil at more frequent intervals, it is only necessary to put one or more lugs on the under side of the wheel, which will operate in the same manner as the lug shown.

What I claim as new is a 1. The combination, with the oil-cup and its valve, of the rotary toothed wheel, the spring-arm D, carrying said valve, the rod G, attached at one end to said valve, connections between said rod and the toothed wheel, and the horizontal lever arranged to actuate said Wheel, substantially as shown and described.

2. The combination, with the casing, the oil-cup, and its valve, of. the toothed wheel, the bell-crank lever, the arm connecting said lever and valve, the lug on the wheel, and the horizontal arm arranged to actuate said wheel, substantially as and for the purpose specified.

3. The combination, with the oil-cup, its valve, and the rotary toothed Wheel, of the bell-crank lever, the arm connecting said lever with the valve, the lug on the wheel arranged to engage one arm of the lever, the springarm, and the horizontal arm carried by the free end of the spring-arm and arranged to actuate the wheel, substantially as and for the purpose specified.

In testimony whereof I affix my signature 3 in presence of two witnesses.

' FRANK KELLER.
